From Micro Eye: ZipOut is an attachment management suite that integrates seamlessly with Outlook. Attachments are the principal component of message traffic and ZipOut will automatically compress these files by as much as 80-90%, dramatically reducing network congestion, connect times, and mailbox bloat.
